General Description
This feature automatically routes outgoing calls over alternate facilities when the first-choice trunk group
is busy. User selects the first-choice route by dialing the corresponding access code, and the equipment
then advances through alternate trunk groups only if the first choice is busy.
Operating Procedure
No manual operation is required.
Service Conditions
1.
No indication is provided to a station user as to whether the call is routed over first-choice or
subsequent choice facilities.
2.
STATION MESSAGE DETAIL RECORDING SYSTEM - RS232C [S-10] may be used in
conjunction with this feature.
3.
Only trunks of the same type may be programmed for ROUTE ADVANCE.
4.
Careful consideration should be given to the use of FX trunks as an alternate facility since, in
many instances, these lines require outpulsing of digits for long distance which the user may not
dial, because he will not know he is connected to such a facility.
5.
The maximum number of routes to be included in a single ROUTE ADVANCE group is 15.
6.
The total number of routes that can be contained in all ROUTE ADVANCE groups is:
IMG (ICS), IMGx
IMGxh, IMGdxh, MMG (ICS), UMG (ICS), UMGx
7.
The same route can be included in two or more alternative groups.
8.
The maximum number of trunks to be included in a route is 255.
9.
No code conversion capability is provided with ROUTE ADVANCE; therefore, the exact digits
(after the access code) the user dials will be sent over the selected trunk, regardless of the trunk
group used. The user will not know what trunk group is selected; therefore, only those trunk
groups that accept the same dialing format may be assigned to a given ROUTE ADVANCE
group.
10. ROUTE ADVANCE occurs only when the dialed code accesses the first-choice trunk group in
the ROUTE ADVANCE list.
11. In most cases, FX trunk groups to a Foreign Numbering Plan Area do not require the dialing of
the FNPA area code. Therefore, these FX trunks may not be used in the same ROUTE
ADVANCE list with local exchange or WATS trunks.
12. TIE Lines cannot be assigned to a ROUTE ADVANCE list that includes CO, FX, or WATS trunk
groups.
13. The dialing party may be either a station line, ATTENDANT CONSOLE [A-3], or a TIE trunk line.
Interactions
1.
When OUTGOING TRUNK QUEUING [O-2] is assigned with the ROUTE ADVANCE feature, if
all trunk groups in one ROUTE ADVANCE list are busy, the call queues on the first-choice trunk
group. Each time the system checks for an available trunk, only the first-choice trunk group is
scanned; if a trunk is not available, the call remains in queue.
